I made this phono preamp a few months back when I first got my turntable and started listening to vinyl. Since, my turntable died on me (it was vintage) and I sold it off for parts because I wasn't sure how to fix it. I was using this preamp in its unfinished state (no enclosure or jacks) during this time (couldn't have more than 5 hours on it, conservatively speaking). I used alligator clips to attach to leads for the input and output. It sounded great at the time (despite turntable issues). Very warm and full sounding. it features:
Four Elna Cerafine 470uF, 35V caps in power supply
two Solen 1.2uF caps in power supply
2x heavy-duty 9V battery clips in series (can use 9V or AAA/AA with appropriate battery holder- I used 16 AA in two holders that will come with the pre)
All Wima MKP 2.5% film caps in equalization network
socketed dual-channel opamp (OPA2604 in there right now)
All Vishay/Dale RN60D and Holco H8 resistors
two Solen 7.5uF output caps
The whole thing is on a 4.5" x 6.25" protoboard. Just to clarify, there are no inputs or outputs attached and no case. It is battery powered right now and I will include the two battery holders for 16 AA (though I don't have any batteries to provide with it). Some DIY work will be necessary for you to finish this amp (solder jacks, case work). You could also change the power supply if you so desired. I simply don't have the time or money to finish the pre, nor do I have a need for it anymore.
If anyone is interested, reply here or send me a PM. I am looking for $40 shipped to US/Canada. Thanks!
